Codex Session Observatory v2.1.0

This release adds Session / Transcript search and moves action feedback from the Status row into Toasts. Find past user requests across local sessions, or highlight and navigate matching content in the current transcript.

Session search

• Search the complete Session Navigator snapshot, including sessions beyond the pages currently loaded in the list. Support both plain .jsonl and compressed .jsonl.zst records.
• Match only actual YOU messages using the existing parser's classification. Codex responses, tool calls, tool results, and metadata are excluded.
• Show matching sessions and their result count while retaining Flat / Hierarchical views, ordering, paging, and session selection.
• Keep the existing discovery boundary under CODEX_HOME/sessions, including the existing exclusions for archives, Guardian reviews, and linked sources.
• Report progress, completion, and unreadable files through Toasts. Ignore superseded searches so older results cannot replace a newer search.
• Submit an empty Session query to restore the complete list. Reload Sessions discovers current files and reapplies the last submitted query.

Transcript search

• Search rendered message bodies that pass the current Filters. Collapsed bodies become searchable when expanded.
• Highlight matches, scroll to the active result, and show the current position and total count. Repeating the same search advances to the next result and wraps after the last match.
• Match displayed Markdown text across inline formatting while preserving line and paragraph boundaries. Keep existing message nodes, link behavior, and Collection snapshots intact.
• Recompute results after filter, collapse, Refresh, theme, or session changes using the last submitted condition. Search preserves the existing filters and Collection state.
• Submit an empty Transcript query to clear its highlights and result position.

Shared SEARCH controls

• Replace the header's Status row with SEARCH, a Session / Transcript selector, a query input, and a magnifying-glass button.
• Keep one shared input across scope changes, with separate last-applied conditions and results for Session and Transcript. Editing or deleting the input, or switching scope, preserves existing results and highlights.
• Apply the input only when Enter or the magnifying-glass button is used. Searches use literal, case-insensitive substrings and ignore surrounding query whitespace.
• Use Ctrl+F to focus the Observatory input and select its existing text while retaining the chosen scope, in place of WebView2's default Find UI.
• Reserve a fixed result area with room for 999 / 999, keeping the input width stable as counts change. Preserve the 44px header row and the three-panel layout.

Toast feedback

• Show action results, progress, warnings, and errors at the bottom right, above the workspace. Hide the idle Ready. message.
• Distinguish Success, Info, Progress, Warning, and Error with status icons and accent colors. Progress uses an animated loading icon and respects reduced-motion preferences.
• Use dark Toasts for Terminal Style / DM Style (Dark) and light Toasts for Markdown Style / DM Style. Apply theme changes immediately to visible notifications.
• Use compact 360px cards with a close button. Allow long errors to wrap and scroll while keeping the panel layout unchanged.
• Dismiss Info and Success after 4 seconds, Warning after 8 seconds, and Error after 12 seconds. Keep active Progress visible until completion, and pause automatic dismissal during mouse or keyboard inspection.
• Preserve status priority, request tokens, and stale-response protection across copying, loading, search, and export operations.

Verification and compatibility

• Pass the complete automated verification: 76 frontend unit tests, 25 browser integration tests, 164 backend tests, and 10 Tauri tests, together with static checks and production builds. Two existing tests that require private local logs remain opt-in.
• Verify Session and Transcript search, filter updates, result navigation, and Ctrl+F in the Windows app using synthetic session records.
• Synchronize application versions and Windows executable metadata at 2.1.0. Remove the trailing period from the Terminal [OK] Latest public version notice while preserving public-release comparison behavior.
• Keep original JSONL records, transcript order, Collection copying, and the Worklog export format unchanged. Search runs locally without a persistent index or external search service.

This remains a portable Windows x64 release with no installer or automatic update behavior.

Code signing policy

See the Code signing policy. The policy is a draft for the SignPath Foundation application; code signing is not enabled. This release remains unsigned.

Codex Session Observatory v2.0.1

This release remembers your Flat / Hierarchical session view and updates frontend dependencies to resolve HIGH-severity security advisories.

Session Navigator preferences

• Save the selected Flat or Hierarchical view on this device and restore it when the app reopens.
• Load the restored Hierarchical view from the newly discovered session snapshot.
• Use Flat when no valid saved choice is available.
• Keep view switching available if the choice cannot be saved, with a warning in Status.

Dependency security

• Update Vite from 8.0.16 to 8.1.6, devalue from 5.9.2 to 5.9.4, and source-map-js from 1.2.1 to 1.2.2, together with the required Vite dependencies.
• Resolve the three HIGH-severity package findings reported by npm audit; the updated dependency graph reports zero known vulnerabilities at release verification.
• These updates cover development, build, and Svelte server-rendering dependencies. The desktop app continues to use a bundled client-rendered frontend.

Verification and compatibility

• Add regression coverage for saved view restoration, invalid values, and storage failures, including app remounts in a real browser.
• Keep original JSONL records, transcript order, Collection behavior, and the Worklog export format unchanged.

This remains a portable Windows x64 release with no installer or automatic update behavior.

Codex Session Observatory v2.0.0

v2.0.0 is a Major Update. Session Navigator, a three-panel workspace, and a redesigned reading and reuse workflow make this a substantial change to how you work with local Codex sessions.

Session Navigator

• Browse local sessions directly from the new Sessions panel, with Flat and Hierarchical views.
• Load additional Flat results as you scroll, or explore the session date folders.
• Open ordinary and ChatGPT Handoff sessions, including .jsonl.zst compressed records.
• Reload the session list independently of the current Transcript and Collection.
• Use a session's context menu to Open, Open Containing Folder, or Export Worklog, including export without selecting that session.
• Show missing local title metadata as Untitled Session, with identifying information in a tooltip. Recent conversation activity emphasizes titles without reordering the list.

Three-panel workspace and desktop workflow

• Arrange Sessions / Transcript / Collection in one workspace with independent side-panel toggles and resizable boundaries.
• Use the available height consistently, with independent scrolling and Top/Bottom controls for each panel.
• Simplify the header around session information, Resume copying, appearance, filters, and common action feedback.
• Move Capture and Transcript Refresh into the Transcript header and streamline Collection controls.
• Separate the Loaded/Idle badge from Reset and consolidate action results, progress, warnings, and errors into the Status line.
• Update the default window to 1360×760, with a 1100×720 minimum.

Appearance and readability

• Add independent Text and Code selectors using fonts installed on Windows, with saved choices and a Default option.
• Use the allocated Transcript width consistently across Terminal, Markdown, DM, and DM Dark.
• Improve DM inline-code and role/timestamp contrast, shared typography, panel boundaries, and icon controls.

Session handling and responsiveness

• Stream plain and zstd-compressed JSONL through the existing parsing flow.
• Fix Refresh control reactivity while preserving Collection snapshots, source order, and panel state.
• Move blocking parse and Export file work away from the native window thread, with controlled file-operation concurrency.
• Preserve existing message DOM across filter changes using stable identities, including distinct duplicate messages.
• Reduce large-transcript DOM overhead by removing redundant ordinary-text wrappers while retaining full content and semantic rendering.

In recorded single-PC synthetic tests, sampled filter DOM reuse improved from 1/20 to 20/20 messages. A large Export's maximum native message-response probe delay fell from 326.8 to 3.4 ms; this measures responsiveness rather than Export throughput. In a separate Terminal test with 2,500 visible messages, HTML elements fell from 107,942 to 77,942, and the median initial-display time across three runs changed from 3,092.9 to 2,831.3 ms.

These are distinct measurements with different baselines, not combined or universal performance guarantees. Large-body redisplay costs remain, and overall application memory savings were not established for the final rendering change. Conditions, validation, and rejected approaches are documented in Performance History.

Compatibility and outputs

• Keep original JSONL records unchanged and preserve transcript order.
• Keep Collection separate from Capture Transcript and complete-session Worklog export.
• Retain existing Worklog format and overwrite safeguards.

This remains a portable Windows x64 release with no installer or automatic update behavior.
